These conferences aim to disseminate the latest research and applications in Circuit Modelling with Applications in Science and Engineering, Control Systems, Signal Processing for Wireless Communication, Computer Applications, New Technologies in Engineering Education, Mechanics of Structural Materials, Urban Planning Strategy and Development, Sustainable Tourism, and other relevant topics and applications. The friendliness and openness of the WSEAS conferences, adds to their ability to grow by constantly attracting young researchers. The WSEAS Conferences attract a large number of well-established and leading researchers in various areas of Science and Engineering as you can see from http://www.wseas.org/reports. Your feedback encourages the society to go ahead as you can see in http://www.worldses.org/feedback.htm The contents of this Book are also published in the CD-ROM Proceedings of the Conference. Both will be sent to the WSEAS collaborating indices after the conference: www.worldses.org/indexes In addition, papers of this book are permanently available to all the scientific community via the WSEAS E-Library. Expanded and enhanced versions of papers published in this conference proceedings are also going to be considered for possible publication in one of the WSEAS journals that participate in the major International Scientific Indices (Elsevier, Scopus, EI, ACM, Compendex, INSPEC, CSA .... see: www.worldses.org/indexes) these papers must be of high-quality (break-through work) and a new round of a very strict review will follow. (No additional fee will be required for the publication of the extended version in a journal). WSEAS has also collaboration with several other international publishers and all these excellent papers of this volume could be further improved, could be extended and could be enhanced for possible additional evaluation in one of the editions of these international publishers.

They are used in a very wide array of application areas - including transport, consumer electronics / electrical appliances, energy distribution, manufacturing systems, etc. Designing embedded systems requires techniques taking into account extra-functional requirements regarding optimal use of resources such as time, memory and energy while ensuring autonomy, reactivity and robustness. Jointly taking into account these requirements raises a grand scientific and technical challenge: extending Computer Science with paradigms and methods from Control Theory and Electrical Engineering. Computer Science is based on discrete computation models, which are by their nature are very different from the analytic models used in other engineering disciplines, because they do not encompass physical time and resources. We discuss the main aspects of this challenge and their associated research directions for different areas such as modelling, programming, compilers, operating systems and networks.

Keynote Lecture I

Distributed Estimation Using Wireless Sensor Networks

Professor Georgios B. Giannakis University of Minnesota

USA

E-mail: [email protected]

Abstract: Envisioned applications of wireless sensor networks (WSNs) include surveillance, monitoring and tracking tasks. These motivate well decentralized estimation and smoothing of deterministic and (non)stationary random signals using (possibly correlated) observations collected across distributed sensors. In this talk we present state-of-the-art algorithms for consensus-based distributed estimation using ad hoc WSNs where sensors communicate over single-hop noisy links. The novel framework reformulates basic estimation criteria such as least-squares, maximum-likelihood, maximum a posteriori, and linear mean-square error, as decomposable, constrained, convex optimization problems that are amenable to distributed solutions. The resultant distributed estimators are provably convergent to their centralized counterparts and robust to communication noise. Besides stationary, the framework encompasses adaptive filtering and smoothing of non-stationary signals through distributed LMS and Kalman filtering.

Abstract: Human eyes receive more than 75% of the total information accessible to the human senses. “There are approximately 45 million blind individuals world-wide according to the World Health Report. Vision loss can be very traumatic, leading to frustration and depression. According to the American Foundation for the Blind (AFB), the rate of unemployment among legally blind individuals of working age residing in the United States (58%) is much greater than that of individuals with no functional limitations (18%). Employment opportunities and independence are scarce for visually impaired individuals. This is unfortunate in view of the fact that ingenious devices [IEEE Spectrum] and information technology (IT) strategies can be developed to help people overcome these barriers and to pursue educational opportunities that will allow them to become productive members of society.” In this talk technological efforts are presented that have the same goal assisting and increasing the visual impaired people’s independence in their working and living environment, and reducing their social neglect ness. In particular, the research effort (called Tyflos) is presented here that is an IT- based wearable system-prototype. It consists of a pair of dark glasses on which two tiny vision cameras, an ear speaker and a microphone are attached. The cameras are connected with a portable computer that carries intelligent software programs. The cameras, under the user’s command, capture images from the surrounding and convert them via software programs into audio or vibrations. The current versions of Tyflos is used as 1) a reader by reading books or the blind user via audio conversion and 2) a navigation by converting 3D images into vibrations for navigation.

Abstract: Depth of field refers to the swath through a 3D scene that is imaged in acceptable focus through an optics system, such as a camera lens. It is a vitally important component of real photographs, and is useful as a tool for drawing the viewer's eye to the important part of the image. Depth of field is equally important for computer-generated images. This talk will provide an explanation of the phenomenon of depth of field and a survey of a variety of techniques to render depth of field effects in computer graphics, with particular attention devoted to the trade-offs between image quality and algorithm efficiency. Algorithms to render highly accurate depth of field effects, such as distributed ray tracing or the accumulation buffer, are sampling methods that use large numbers of samples, with high computational cost. Sampling is inherently slow because it effectively requires rendering the scene many times, which multiplies the render time by a potentially large factor. Faster algorithms are based on a post processing approach, which operates in image space. Post process methods operate on 2D images along with depth information, rather than working with a full 3D object representation as the sampling methods do. Consequently, post process methods struggle to accurately simulate the underlying optical process, and tend to suffer from artifacts or avoid those artifacts at a large cost. The talk will include an analysis of the nature of these artifacts. Brief Biography of the Speaker: Brian A.

Plenary Lecture II

Advances in Semiconductor Devices and Their Growing Use in Electrical Circuits and Systems

Professor Noel Y. A. Shammas

Staffordshire University Faculty of Computing, Engineering and Advanced Technology

UK [email protected]

Abstract: The main aim of this investigation is to asses the suitability of modern power semiconductor devices for pulse power applications. Pulse power system involves the storage of energy, which is released in form of high power pulse to the load by means of a switching device. Hence the basic components of pulse power system are an energy storage element, a switch, and a load circuit. The energy storage is usually either an inductive or capacitive nature. The limiting device in a pulse power system is often the switch, which limits the pulse peak power and the repetition rate. The switch element in this case is very special and falls into two basic categories: 1-Vacuum and gas filled switching tubes, 2- Solid-state (semiconductor) switches. The conventional approach in pulsed power designs is to use spark gap and gas filled switches such as thyratron and ignitron, because they truly possess the required characteristics for high power application. However, these devices have limited lifetime, high cost, low repetition rate and high losses. On the other hand high power semiconductor devices have under gone continued improvement in switching speed, voltage and current ratings and thus are replacing the conventional gas filled devices in some applications. Solid state devices are considered environmental friendly since they do not contain nasty gases and have perceived higher reliability than gas filled devices. In this paper, a complete overview of vacuum and gas filled switches and solid-state switches will be given. Very rarely these types of power semiconductor devices are characterised for pulse power applications and so the task of dimensioning a device simply from the datasheets is somewhat difficult and time consuming. Different methods for assessing their suitability will be described and a new technique to rapidly dimension the semiconductor device for pulse power application will be presented.

Brief Biography of the Speaker: Noel Shammas is currently a Professor in Microelectronics and Solid-State Power Semiconductor Devices in the faculty of Computing, Engineering and Advanced Technology, Staffordshire University.

Vibro-acoustic Techniques to Diagnose Complex Electromechanical Structures

Professor Francesco Muzi

Department of Electrical Engineering and Computer Science University of L’Aquila

ITALY E-mail: [email protected]

Web site: http://www.diel.univaq.it/people/muzi/

Abstract: A diagnostics procedure based on signal processing of acoustic emissions aimed at investigating complex electromechanical structures is presented. Acquired signals emitted by a structure can be activated by either natural or artificial stimuli; when using artificial and known stimuli, that is to say, stimuli linked to a set of parameters representing “state vectors”, the diagnostic method may prove to be very accurate. Signals are processed through the following stages: acquisition, segmentation, parameterization, classification and recognition. An a priori definition of the possible classes to which the system under investigation might belong is required. By means of a consultation of a predefined digital vocabulary of possible anomalies, the analysis process establishes the statistical “closeness” of the case examined to a reference model in the vocabulary and subsequently identifies the belonging class of the apparatus under checking. If the involved physical phenomena are well known, the classification can be performed using knowledge-based techniques, otherwise statistical procedures are recommended. In the past, diagnostic processes allowed to define only the object state at the moment of the investigation; nowadays, thanks to the availability of low-cost, huge digital memories and relevant power computation, the diagnostics processes allow also to predict the residual life expectation of complex jointed structures. The proposed monitoring and diagnostic method allows a time-by-time assessment of the evolution of power system components from the installation to their life end. The normal operating apparatuses can be monitored and checked from a remote, dedicated diagnostic center where information is received directly from the field. The suggested monitoring and diagnostic system allows one to usefully schedule preventative maintenance, reduce costs, and improve the quality of electric power systems. Many complex structures were examined, and some relevant real diagnostics cases concerning power transformers, power circuit breakers, and transiting electric trains are illustrated and discussed.

Brief Biography of the Speaker: Francesco Muzi is a professor of Power Systems at the University of L’Aquila, Italy, where he has also the scientific responsibility for the Power System Group. His main research interests concern Power systems transients and dynamics, Power quality in distribution systems, Power system reliability, Electromagnetic analysis, and Power systems diagnostics and protection.

Plenary Lecture IV Electromagnetic Low Frequency Radiation from Natural Phenomena - Data Analysis and

Modelling

Professor Ernst D. Schmitter University of Applied Sciences

Department of Engineering and Computer Sciences Albrechtstr. 30, 49076 Osnabrueck

GERMANY

Abstract: Can severe weather conditions, volcanic eruptions or even earthquakes be predicted from monitoring and analyzing electromagnetic radiation especially in very and ultra low frequency ranges? What signatures in this frequency range leave solar wind, solar flare eruptions or gamma ray bursts from distant stars within the earths magnetosphere and ionosphere? The propagation properties of very low, extremeley low and ultra low frequency radiation (VLF/ELF/ULF, i.e. 30 kHz down to some milliHz) within the earths magnetosphere, ionosphere and lithosphere allow to deal with these questions and a lot of research has been done during the last decades. In some cases the generating physical process is obvious – as for example VLF sferic signals from lightnings. In other cases reliable modelling and confirmation is due yet - as with electromagnetic earthquake precursor signals. This survey will try to mediate some aspects of the advanced data analysis and data modelling procedures used to gain information out of the received signals despite of a usually very noisy background. Fourier- and wavelet transform based as well as statistically based features are used as input to neuro-fuzzy classifiers together with physical process models to form hybrid approaches to these complex systems.

Brief Biography of the Speaker: Dr. Schmitter is professor for mathematics and software technology at the University of Applied Sciences Osnabrueck, Germany since 1990. He is a member of the faculty of Engineering and Computer Sciences and teaches courses on applied mathematics, simulation (for example Finite-Element-Methods) and data analysis. He wrote several books in the computational intelligence area and published papers on data and signal analysis and modelling topics applied to material sciences and geophysics.

Abstract: Based on biological prototype of human brain and improved understanding of the functionality of the neurons and the pattern of their interconnections in the brain, a theoretical model used to explain the information-processing characteristics of the cerebellum was developed independently by Marr (1969) and Albus (1971). Cerebellar model articulation controller (CMAC) was first proposed by Albus. CMAC is a learning structure that imitates the organization and functionality of the cerebellum of the human brain. That model revealed the structure and functionality of the various cells and fibers in the cerebellum. The core of CMAC is an associative memory which has the ability to approach complex nonlinear functions. CMAC takes advantage of the input-redundancy by using distributed storage and can learn nonlinear functions extremely quickly due to the on-line adjustment of its system parameters. CMAC is classified as a non-fully connected perceptron-like associative memory network with overlapping receptive-fields. It has good generalization capability and fast learning property and is suitable for on-line application of control systems. This talk introduces several CMAC-based adaptive control systems; these control systems combine the advantages of CMAC identification, adaptive control and robust control techniques. In these systems, the on-line parameter training methodology, using the gradient descent method and the Lyapunov stability theorem, is proposed to increase the learning capability. Moreover, the applications of these systems in control problems are demonstrated. Simulation results illustrate that the introduced CMAC-based control systems can achieve favorable control performance.

Plenary LectureVI

On Dynamical Systems Describing Tumor Growth under Novel Therapies

Professor Urszula Ledzewicz Department of Mathematics and Statistics, Southern Illinois University Edwardsville,

Edwardsville, Illinois, USA


Co-Author

Professor Heinz Schattler Department of Electrical and Systems Engineering,

Washington University, St. Louis, Missouri, USA

Abstract: In this talk dynamical systems arising in biomedicine describing various treatments of cancer will be discussed. Mathematical models for cancer treatments have a long history, but with the development of medicine new challenges in modeling and the analysis of these models are appearing. Here novel cancer treatments and the mathematical models that describe their dynamics as systems of nonlinear ordinary differential equations will be presented. The focus primarily will be on mathematical models for tumor anti-angiogenesis. The importance of this novel treatment is that by targeting the cells of the vascularization of the tumor rather then the tumor itself, it is not prone to drug resistance and as such has been a topic of active research both in medicine and mathematical biology. In the talk a class of mathematical models for anti-angiogenesis will be analyzed. The nonlinear dynamics in these models illustrates the growth of the primary tumor volume and its corresponding vasculature as well as the effect of the control functions representing anti-angiogenic treatment on this growth. Following the analysis of this system with constant doses of the drug, the optimal control problem of how to schedule an a priori given amount of angiogenic inhibitors so as to minimize the primary tumor volume will be considered. Examples of optimal protocols resulting from the analysis will be given. Then, following medical research on so-called combination therapies, the model will be augmented to include the effect of traditional chemotherapy on the system. Due to the multi-control aspect, even with simplified dynamical equations, this becomes a challenging problem mathematically and some initial results about the structure of optimal controls will be presented.

Brief Biography of the Speaker: Urszula Ledzewicz received her Ph. D in 1984 from the University of Lodz, Poland. Since 1986 she has been holding academic positions in the United States, first as a visiting faculty at Louisiana State University, Baton Rouge, and then at Southern Illinois University, as a tenured faculty in the rank of the Full Professor since 1995. Her research area is primarily control theory and optimization, but in more recent years she became interested in applications of the methods of optimal control and systems theory to biomedicine. Currently her main direction of research includes analysis of systems describing dynamics of cancer growth under various treatments like chemotherapy or anti-angiogenesis. She is a member of five editorial boards including Discrete and Continuous Dynamical Systems, Series B, and Mathematical Biosciences and Engineering and author or co-author of close to 100 publications in refereed journals and proceedings of international conferences. She was invited to present lectures at various mathematical and engineering oriented conferences as well as was a member of the organizing committees or co-organized sessions or mini-symposia at several of them like IEEE Conferences on Decision and Control (CDC), Mathematical Theory of Network and Systems (MTNS) or World Congress of Nonlinear Analysts (WCNA).

Abstract: Almost in any field of science and technology some sort of stability problem can appear. Instability and chaos are certainly the most important phenomena which should be treated before any other aspect of reality will be attacked. Hence it is not very surprising that a broad variety of approaches to the problem of stability, instability and analysis of chaotic phenomena exists. Many of the most popular techniques in the field of stability and chaos are in a certain sense related to the work of A.M.Lyapunov and can be seen as energy oriented. The Tellegen’s theorem is one of the well known forms of energy conservation statement in the field of electrical engineering. The most important feature of Tellegen’s approach is the fact that the energy conservation principle holds without any regard to physical nature of constituent network elements. This is the key idea of the proposed approach to problems of dissipativity and chaos. The first situation arises if an energy function E[x(t)] of a given system is known in a mathematical form. In such example the time evolution of internal energy along any system motion can be described, and an energy monotonicity test can be used. In the proposed lecture a physically motivated signal-system-theoretic approach, based on a generalisation of the well known Tellegen’s principle of electrical circuits will be presented. Two fundamental concepts are of crucial importance in the proposed approach. The first one is the concept of strongly non-linear power-informational interactions, and the second one is the notion of state space energy vector, inducing the system state-space topology. All computations, including numerical solutions of differential equations, were done using MATLAB.

Abstract: Since the obstruction of complete integrability conditions (path independent curvilinear integrals) is very strong, the control problems for multi-time first order PDEs were studied only in the discrete context. Now, to preserve the geometrical character of the problem, we present a continuous approach for the controllability and observability properties of multi-time completely integrable linear PDEs systems (holonomic evolution), overcoming the extant mathematical prejudices regarding the importance of a multi-time evolution. Our geometrical arguments show that each basic theorem has a correspondent in the case of single-time linear controlled ODEs system. The main results include controllability criteria and the equivalence between controllability of a PDEs system and the observability of the dual PDEs system. All of these show that the passing from controlled single-time evolution to the controlled multi-time evolution is not trivial. Changing the geometrical language, the case of nonholonomic evolution can be recovered easily from our theory.

Abstract: This plenary talk will present research advances in neurotechnology that are aiming to improve the quality of life of patients suffering from neurological disorders. We will focus on epilepsy as a typical severe disorder. Enabling technologies will be discussed that begin with intracranial monitoring techniques, such as IEEGs, and the analysis of signals to determine precursors to an epileptic seizure. The intent is to detect but primarily to predict in advance the seizure initiation. Upon detection/prediction, an electrical signal is transmitted to the areas of the brain suspected as the seizure source in order to terminate the seizure before is affects the patient. We will describe clinical results of an implantable device currently under development to implement the monitoring, signal analysis and intervention methods.

Abstract: Metamaterials are been recently very used at telecommunications structures, and are defined as artificial effectively non-homogeneous electromagnetic materials with desired bi anisotropic dielectric and magnetic characteristics. In this paper the bilateral fin line and planar antennas with EBG – Electromagnetic Band Gap – metamaterial substrate is analyzed using the TTL - Transverse Transmission Line, concise full wave method. Fin lines are widely used as a millimeter wave component due to its various advantages such as reduced size, weight, and low cost and in addition because it interfaces easily with other millimeter wave circuits. This letter demonstrates an application of the EBG metamaterial: an efficient bilateral fin line and microstrip antennas. the analysis is made using the TTL method and the metamaterial substrates. This objective of this presentation is to show the effect of dielectric anisotropy on bilateral finlines shown in Fig. 1 and antennas. the paper discusses the effect of anisotropy, on effective dielectric constants, attenuation constant and the pattern E and H fields by applying the anisotropy one by one in all three directions. the EBG medium can not be characterized by assigning a single permittivity and permeability value for throughout the finite structure. In other words, the parameters depend on the spatial coordinates and this causes spatial dispersion. As a result of this, the medium will not be homogenous. for a non-homogeneous structure, the incident wave undergoes a process of multiple scattering. the substrate shown in region 2 of Fig.1 is modeled by utilizing bianisotropic tensor properties, which are expressed as:

To calculate the numerical results a computational program in Fortran PowerStation language, according to the theoretical analyses was developed. Compared to other full wave methods, the TTL is an efficient tool to determine the fin line and antennas characteristics, making possible a significant algebraic simplification of the equations involved in the process, and reducing the computational time.

Plenary Lecture XI

Queuing and Loss Network Models: Computational Algorithms and Asymptotic Analysis

Professor Hisashi Kobayashi

Princeton University, USA E-mail: [email protected]

Abstract: Queueing network theory has been successfully applied by computer and communication system modelers to represent the inherent contention and congestion in multiple resource systems, to identify the system bottlenecks, and to assess the performance limits. A queueing network model provides a suitable framework for analyzing the performance of “connection-less services” in a packet switched network. the so-called “product-form” networks such as Jackson network and its generalizations, allow such performance metrics as throughput and the mean delay to be represented by a ratio of the “normalization constants” with different arguments. Connection-oriented services, such as the conventional circuit-switched telephone networks and end-to-end flow connections over the Internet can be properly represented by loss network models. the loss network theory is a relatively recent development, and can be viewed as an extension of the classical Erlang and Engset loss models. We will discuss interesting relations between queueing networks and loss networks, and show that the computational algorithms developed for queueing networks are equally applicable to the normalization constants and performance metrics in loss networks as well. Finally, we will discuss the case of large systems, where even most efficient algorithms for exact solutions are computationally infeasible. Recent development for approximation techniques and asymptotic performance limits will be reviewed.

Plenary Lecture XII

Intrusion Detection in Modern Optical Networks and Countermeasures

Professor Stamatios Kartalopoulos

University of Oklahoma, USA


Abstract: Optical networks are considered to be intrusion-resistant by virtue of the fiber medium. the common belief is that the optical fiber is difficult to tap, as compared to copper wire and to wireless media. In fact, this is a simplistic view because stripping a cable and tapping a fiber with tools that are commercially available is a relatively simple task to the sophisticated intruder. Moreover, because the fiber link is many kilometers long, the fiber cannot be guarded; this presents a tremendous opportunity and flexibility to the intruder to select the point of intrusion unnoticed. Therefore, it is important that the network is sophisticated enough to monitor and detect intrusions, differentiate from possible component failure and degradation, and upon detection of fiber attacks, it executes automatic countermeasures, outsmarting the intruder. In this talk, we describe automatic intrusion detection methods and countermeasure strategies in modern optical networks.

It turned out, that there are common methods of redundancy creation in different kinds of art like painting, architecture, music and speech. It is shown the common peculiarities of human processing of video and audio information. On the other hand, due to the limited bandwidth in communication channels, transmitted signals must be compressed. This begs the question – what should be transmitted in these types of signals, if a large part of them is removed by the system controlling the sensor-brain?

Plenary Lecture XIV

New Directions in the Design of Secure Wireless Systems Using Chaotic Signals and Interference Mitigation Techniques

Professor Peter Stavroulakis Technical University of Crete,

Telephone +30 28210 37333, +30 210 9651154 E-mail: [email protected]

Abstract: One can say that the subject of security is as old as the subject of communications. In the area of wireless communications, Microwave radio from its introduction in the late 1940 to the present has become one of the primary media for transmitting information from point to point and from a point to a given area. the advent of Satellite communications technology in 1962 and consequent sharing of bands between satellite and radio relay coupled with the explosive growth of Microwave radio routes and mobile communications has led to increased sharing of frequency spectrum and to generation of increased mutual interference. This added interference is playing a dominant role in limiting the capacity, efficiency, reliability, security and cost of modern communication systems. Thus we now have an added problem in Wireless systems which for Satellite Communications has been coded as space security. Security is of major concern of the environment in which various communication systems coexist either in the same or adjacent frequency bands and is also caused by non-ideal mainly nonlinearity mechanisms utilized in the process of communication. the subject of interference has become again an important area of major concern in recent years related to Security due to the widespread use of mobile and wireless terrestrial systems for voice communication. Having studied and solved the problem of sending the information reliably, it was then necessary to study ways to transmit the information securely. for wireless mobile systems this problem was partially solved by using various encryption techniques. In this tutorial we shall present a review of the areas that require further study and we will show for the first time why the existing security mechanisms including cryptography do not necessarily solve the security problems in various wireless systems. We shall propose ways to move forward using as an example a new methodology based on Chaotic techniques. This methodology is based on two recent books by the author and an International Patent by the author which what was thought as an impossible task i.e to make chaotic signal based secure communications robust is now proved possible. This Tutorial will benefit young researchers, designers of large scale Secure Telecom Systems such as those used in World class events as are the Olympic Games and University Instructors who are seeking to put together instruction material for new courses.

Plenary Lecture XV Computational Intelligence Solutions for Biometrics

Professor Victor-Emil Neagoe Depart. of Electronics, Telecommnunications and Information Technology,

Polytechnic University of Bucharest, Splaiul Independentei 313, Bucharest, Romania

Abstract: The word biometrics is a combination of the Greek words bio and metric. When combined, it means “life measurement.” Biometrics concerns the study of automated methods for identifying an individual by measuring one or more physical or behavioral features of him. Certain physical human features or behaviors are characteristics that are specific and can be uniquely associated to one person. Common physiological biometric traits include: fingerprints, hand geometry, retina, iris, DNA and facial images. Whereas, common behavioral biometric traits include: handwriting, voice print, gait, and keystroke rhythms. Nowadays biometrics is rapidly evolving; it becomes more and more attractive and effective in critical applications, such as to create safe personal IDs, to control the access to personal information or physical areas, to recognize terrorists or criminals, to study the movements of people, and to monitor the human behavior. Several governments are now using or will soon be using biometric technology. The U.S. INSPASS immigration card and the Hong Kong ID card, for example, both store biometric features for authentication. Computational intelligence (CI) is a fastmoving research field with approaches primarily based on neural networks, machine learning, fuzzy logic, genetic algorithms and evolutionary computing. Computational intelligence (CI) technologies are robust, can be successfully applied to complex problems, are efficiently adaptive, and usually have a parallel computational architecture. For those reasons they have been proved to be effective and efficient in biometric feature extraction and biometric matching tasks, sometimes used in combination with traditional methods. In this lecture we survey two kinds of major applications of CI in biometric technologies: CI-based feature extraction and CI-based biometric matching. We also present the original contribution of the author regarding some CI solutions for facial image recognition and iris identification.

Plenary Lecture XVI Post Modern Ubiquitous Information Society

- Bridging the gap between human and computer -

Professor Norio Shiratori Research Institute of Electrical Communication (RIEC)

Tohoku University, JAPAN

Abstract: Famous Russian economist, Nicolai Kondratiev envisioned a long term (50 to 60 years) economic cycles of boom followed by depression, known as "Kondratiev waves", or grand supercycles. These cycles are closely related to the innovation of new technologies and its wide spread applications. The last boom was in 1960s with the invention of semiconductors and subsequently the introduction of computer. According to Kondratiev time-cycle, new technology and the consequent next economic peak would appear around year 2025. By that time, with the advancement of computer and communication technologies we can perceive a transformation from the present Information society to a new society, that we named as Symbiosis society. We have already witnessed that, invention of new technologies has made a huge impact on our life style and the society itself. Though it may provide various advantages and convenience, at the same time many social problems have also arisen. For some particular group of people, this technological development may not be as helpful as the rest. As they will be unable to take the full advantage of the benefits of information and facilities available. Actually it may pose anxiety and inconvenience to various layers of the society in different ways. To overcome these problems and to close the expected gap between human and computer a new information and communication paradigm is proposed, named as Symbiotic Computing. To overcome the above mentioned shortcomings and the subsequent problems, at the same time strengthening the power of advance ubiquitous computing environment, a new paradigm, called Symbiotic Computing is created. Based on this novel idea of Symbiotic Computing, Symbiosis Society can be realized, where human and ubiquitous information environment can coexist providing necessary cooperation to each other and close the gap between these two entities. We construct a symbiotic computing model and an architecture of symbiotic space for achieving the concept of symbiotic computing. Basic technologies for realizing the model and architecture are also developed. Moreover, we evaluated our proposal through developing a few applications and performing trial experiments in prototype system.

Plenary Lecture XVII Symbolic Computing in Engineering Simulations and Education

Abstract: Symbolic computations nowadays still extend the area of potential applications in a variety of the fundamental and applied sciences and, especially, in different branches of the modern engineering. Now, using such computer systems as MAPLE, MATHEMATICA, MATLAB or MATHCAD for instance, it is possible to solve the complex systems of partial differential, make precise visualizations of the observed dynamical systems or to perform some statistic or stochastic simulations of the non-deterministic systems. The quality of those computer environments in terms of interoperability with the other programs (like the Finite or Boundary Element as well as Finite Difference Methods source codes), computer time cost, visualization tools and the number of ready-to-use available applications still dramatically increases. Relatively simple differentiation methods, both symbolic and numerical, frequently leed the users to apply symbolic computations programs to sensitivity and optimization studies, whereas a wide range of statistical tools enables uncertainty inclusion and estimation in various unstable systems computations finished with the reliability prognoses. At the same time symbolic computer systems are very valuable educational tools for mathematicians, physicians and the engineers because the students after primary demonstration of some problem solution may easily follow the teacher, whereas the powerful visualization may help to understand the methods not only by numbers and symbols but also using the graphs and animations. Therefore, the main aim of the lecture is to make a review of the recent advances in designing, capabilities, implementation, various machines and operating systems performance as well as the applications for the symbolic computer programs using, as the example, the system MAPLE. The recent research applications in composite materials modeling and stochastic analysis will be shown together with the case studies used in the civil and mechanical engineering practice and some examples used in undergraduate, graduate and doctoral courses. Some new ideas concerning the symbolic computations packages and their general ideas will be also discussed.

Abstract: Medical Intelligent e-Learning Systems (MILSs) are concerned with the construction of intelligent software that performs diagnosis and make therapy recommendations. Unlike other medical applications abased on other programming methods such as purely statistical methods, MILSs are based on symbolic models of disease and their relationship to patient factors. Many types of MILSs are in existence today and are applies to different medical tasks, e.g. generation alerts and remainders, diagnosis assistant, therapy critiquing and education . This talk presents some of the intelligent technologies used in developing intelligent medical learning systems at Ain Shams University, Cairo, are discussed as well.

Plenary Lecture XIX Super-Object-Oriented Programming and Simulation

Professor Eugene Kindler

Profesor of applied mathematics, University of Ostrava, Faculty of Science, Dept. of Computers and Informatics,

CZ - 701 03 Ostrava, 30. dubna no. 22, Czech Republic


Abstract: One applies simulation namely in studying complex systems and for that purpose special programming techniques were developed, among which the object-oriented programming (OOP) passed the domain of simulation over and became a universal technique of programming and of representation of concepts. A man-made system S designed in a modern way often uses a computer C for controlling its operation and – in case the controlling is complex – it uses also simulation and/or OOP. If such a man-made system S is simulated during its design phase, C should be reflected in the used simulation model M, together with its operation, namely with the (simulation) model m and/or the represented concepts used by it; this statement can be exactly proved. So the “internal” model m should be “nested” in the “external” model M and often the system r of concepts represented for the purpose of m should be “nested” into the system R of concepts represented for the purpose of M. The psychology demands the authors of the models to introduce the same names of concepts, of functions and of elements for both the models M and m, although they essentially differ by their own relation to the simulated reality; for example, they have their own (mutually different) time flows; moreover, a danger of a fatal error called transplantation exists, consisting in assigning a name qualified in one of the models to an element belonging to the other one. There is a technique called super-object-oriented programming (SOOP) that allows secure and decipherable producing of such “nesting” models. It consists in enlarging the OOP by “life rules”, i.e. algorithms according the instances of the concepts should behave, and local classes, that enable an instance E of a class to carry classes “nested” in it. In M, E can simply model a modeling/simulating computer (or even a formalized human “manager” existing inside the system reflected by M, who time to time anticipates possible future consequences of his own decisions). Surprisingly, SOOP was discovered already 41 years ago together with the OOP. The principles of solving obstacles in the nesting simulation models will be presented. The author led some works oriented to simulation of the sea harbors (especially container terminals), of the production halls equipped with auto-routed vehicles, and of the hospital sections, and in the Czech Republic and France such techniques were followed, namely in developing special “quasi-parallel” methods of optimizing and of nested simulation models of public transport, of circular conveyors and of systems of demographic development. Their details will be presented in special papers of their authors.

Brief Biography of the Speaker: Eugene Kindler was born in 1935, studied mathematics at Charles University in Prague, (Czechoslovakia) and then computer science at the Research Institute of Mathematical Machines in Prague.

In parallel, he worked with a new University of Ostrava. Since 2006 he has been pensioned, collaborating with the same Ostrava University as external specialist in various research projects and in doctoral studies. During 1967-1973 he was responsible for special projects on information processing in radiation security and during 1973-1989 he was head of teams oriented to the fundamental research of modeling techniques. During 1995-2000 he represented Czech Republic activities at two COPERNICUS projects sponsored by the European Commission and oriented to sea harbor modernizing with use of modern information technology. Beside many shorter professional stays at foreign institutions, he worked as visiting professor with the University of Pisa (Italy, one year around 1969) and with West Virginia University (Morgantown, USA, one year around 1993), as invited professor and then as holder of French government professor scholarship with Blaise Pascal University (Clermont-Ferrand, 9 moths, around 1995 and 1998) and with the University of South Brittany (Lorient, France, 3 times one months in 2002-2004), and as a hosting lecturer with Humboldt University (Berlin, 3 months in 1983). His main professional interest is object-oriented simulation of discrete event systems, namely of those using their own private models for anticipating their future states. His private hobby is the chant originated during the first millennium A.D. in Europe and certain Near East Asian countries.

Plenary Lecture XX Heterogeneous Reconfigurable Chip Multiprocessors for Embedded Systems

Professor Sotirios G. Ziavras

Associate Chair of ECE (in charge of Graduate Programs) Director of the Computer Architecture and Parallel Processing Laboratory (CAPPL)

Department of Electrical and Computer Engineering (ECE) New Jersey Institute of Technology

Newark, New Jersey U.S.A.


Abstract: Chip multiprocessing has recently become a common practice in processor design. With ever increasing concerns for energy consumption, performance-energy trade-offs are often necessary, especially in the design of real-time embedded systems. Multiprocessor heterogeneity is a successful design paradigm for high performance and energy conservation with embedded systems. Performance and energy analyses will be presented for an in-house developed FPGA*- based mixed-mode heterogeneous chip multiprocessor, where the SIMD (Single-Instruction, Multiple-Data) and MIMD (Multiple-Instruction, Multiple-Data) parallel computing modes can be realized simultaneously or distinctly. The presented performance-energy trade-off techniques are based on the observation that SIMD and MIMD tasks involve substantially different amounts of computation and communication with different execution time and energy behaviors. Experimental results on Xilinx FPGAs demonstrate the effectiveness of the proposed approach. To conserve space and power as well as to incorporate dynamic adaptability in embedded systems, it is important to utilize hardware components as best as possible. The hardware customization of application kernels reduces the execution time and potentially the power consumption. Reconfiguring the same hardware to facilitate various customized kernels as execution proceeds greatly reduces the space requirements. When the kernel execution is carefully scheduled considering also the reconfiguration overheads, the obtained performance gain can offset such overheads. A policy and experiments will be presented of customizing and reconfiguring multiprocessor hardware for embedded benchmark kernels implemented on FPGAs. The results reveal substantial performance improvement and resource conservation. * FPGA: Field-Programmable Gate Array

Valencia - SPAIN E-mail: [email protected]

Abstract: Collaborative learning an educational strategies that should be incorpored in all plan of studies in the university careers. It is considered as one of the main learning strategies in the Bologna process. In collaborative practices students are divided in groups to do their activities and they are evaluated by their productivity. The fact of doing a common task in which each one of them depends on and is accountable to each other, prepare the students personal and socially for the enterprise environment. It is demonstrated that this educational strategy improves students' communication habilities, enhances the students responsability and shows them how they should organize for any enterprise. This talk will review some practical examples and several study cases, and how they have been set up in order to obtain the best result. Collaborative learning basic elements such as objetives, environment, motivation, kind of process, individual contribution and group process steps, will be discussed. Examples and cases reviewed will show their benefits and the students results given when it is used.

Science Teachers’ Collaborating Learning for Scientific Literacy: from Practice to the Practice

Dr. Michail Kalogiannakis Researcher University Paris 5 - René Descartes

Laboratory: Education et Apprentissages Web site: http://labo.eda.free.fr/article.php3?id_article=11


Abstract: In the information society, the ability to collect, develop, exchange, store and manage information from various and dispersed data along with the ability to generate additional information is essential. Distance learning is not a new phenomenon. The term distance learning is extensively used by colleges and universities to describe remote delivery of course contents. In the last three decades a rapid development of information and communication technology (ICT) has opened new horizons for distance learning providing new magnificent opportunities for mankind in the area of education. The traditional organisation of education creates often practical difficulties in using new technologies in class. The limited impact of ICT has as much to do with science teachers’ attitudes and skills as with access to equipment. Science teachers should prepare their students for a multiplicity of roles that will be called to play in the future. We argue that there is a great need to restructure science teachers’ education if we wish school science to serve the purpose of scientific literacy. The mailing lists can be used as collaborative work tools for interaction and dialogue creating educational communities. Generally speaking, online communities can offer a lot of opportunities to teachers which are comparable with face to face meetings. Those who communicate on-line maintain a variety of links, exchanging information, emotional aid creating complex relationships. Subscription to and participation in mailing lists could be a part of science teacher’s on-going professional development. This particular individual commitment follows the logics of action of a social experience: integration, strategy and subjectivation. Science teachers belonging to mailing lists have specific interests in professional training, ICT and knowledge. Science and technology are two of the most important areas of the modern human culture. If science and technology education is meant to have any functional role to play in the future lives of the students, then a holistic reorientation of both its content and the association with that pedagogical approach is required. Although we can not predict how virtual learning environments will influence learning effectiveness, an important point to consider is that, for sciences teachers, a virtual space is an open space, a space where they can try new approaches. Teaching has always been an individual work: teachers do not collaborate a lot; they rarely attend to each others lectures, and they rarely exchange teaching material. The challenge here is to turn teaching into a collective performance using the paradigm of the mailing lists.

National University of Malaysia (UKM), Bangi, MALAYSIA Phone Number: 03-89216843 Fax Number: 03-89216960


Abstract: This paper discusses a comprehensive study of employers’ perception and expectation of Malaysian engineering graduates towards assessing measurable qualities. To have better overview in this issue, a survey on the needs, perception and expectation of Malaysian industries towards graduate engineers is conducted. In order to create a smoother transition from education to practice, some argue that engineering education should put more emphasis on the engineering-based knowledge. Thus, this study investigates also the gap analysis which is defined as the difference between expectation and perception among majority of Malaysian industries towards existing engineering graduates. For the purpose of this paper, both technical and generic attributes are analyzed and discussed. A total of 422 companies from various industries in Malaysia were chosen for the face-to-face interview sessions using a set of questionnaires. The respondents were mainly come from high ranking personnel in their firm. The outcomes of this study will later be considered as a revision guideline for the engineering education curricula of Malaysian Institutions of Higher Learning.

Brief Biography of the Speaker: Dr Azami Zaharim worked first 13 years .as a lecturer in the University of MARA Technology (UiTM) before joining the National University of Malaysia (UKM) in the year 2003. He has published more than 50 papers in Journal and proceeding at the national and international conferences. He is currently active involve in outcome based education approach at the national level. He is also involved in the research for the future of engineering education in Malaysia 2006 under the Ministry of Higher Education of Malaysia.

Plenary Lecture XXIV

Case Study as a Teaching Tool for Analysis of Real-World Problems: Applications of Mathematics in Engineering and Business Education

Professor Andrei Kolyshkin

Department of Engineering Mathematics and Riga Business School Riga Technical University

LATVIA [email protected]

Abstract: Case study method is widely used in many business and law schools around the world to teach students about their fields using real-world business situations known as cases. The case method develops students’ analytic and problem-solving skills. It is usually focused on an interest-arousing situation and stimulates students’ active learning and participation. However, the case study method is not so widely used in engineering education. In the present paper we discuss some issues related to the use of mathematics as a tool for analysis of real-world problems through case studies. First, a brief history of case study method is presented. Second, advantages and disadvantages of case study methodology are discussed. Our experience in teaching mathematics to engineers shows that in order to be useful for engineering students, a case study should satisfy the following conditions: (1) The case should be based on a real-world problem; (2) Relatively simple mathematical models should be used to analyze the case; (3) Solution of complex, real-world problem requires knowledge of several mathematical methods (both analytical and numerical); (4) The results should be compared with experimental data. Several examples of real-world problems which can be solved with relatively simple mathematical methods are discussed in the paper such as leak and blockage detection in pipelines and bacteria regrowth in water distribution systems. Managerial statistics course is one of the core courses in many MBA programs. However, many students consider this course as one of the most difficult courses. There are several reasons for that: (1) many students have a negative impression about statistics course at undergraduate level; (2) some of them do not consider statistics as a useful tool in managerial decision making; (3) not all the students have solid background in mathematics and related areas. Case study as a teaching tool in these situations can help to overcome psychological barriers and stimulate students’ active participation and develop necessary problem solving skills. Examples of real-world business situations which can be analyzed by means of statistical methods are given in the paper. Advantages and limitations of case study method are discussed.

Brief Biography of the Speaker: Andrei Kolyshkin received his undergraduate degree in Applied Mathematics in 1976 at the Riga Technical University. In 1981 he received a Ph.D in differential equations and mathematical physics at the University of St. Petersburg. Andrei Kolyshkin is currently a full professor at the Department of Engineering Mathematics at the Riga Technical University. His current research interests include investigation of stability problems in fluid mechanics with applications to open-channel flows and transient flows in hydraulic systems. He is the co-author of three monographs published by Academic Press and CRM. Andrei Kolyshkin has participated in more than 30 international conferences and has published amore than 50 papers in refereed journals since 1990. As a visiting professor and visiting researcher he spent a few years at the University of Ottawa and Hong Kong University of Science and Technology.

Plenary Lecture XXV

From The Real World To Models And Paradigms In Parallel Scientific Computing

Assoc. Prof. Ion Cârstea University of Craiova,

ROMANIA [email protected]

Abstract: The people are not isolated actors on the world scene. They enter in competition and co-operation. This real scenario is the basis of the parallel computing and finally, the basis of the parallel computers. The work in the team with the principal characteristics, the co-operation and the collaborative competition, is an education model. Cooperation and collaborative competition must be the basis of the educational process from universities, aspects that are often ignored in educational politics from Romania. The nature models are the starting points in many human projects like the parallel processing of data. The nature models must be the starting points of the educational process with emphasis on the inter-human relations. The real world offers a lot of models and paradigms for engineers in the area of the computer science and engineering. In a high- performance education we can not ignore the large computing power of the advanced computers as the parallel computers. To ignore the high-level information technology is an anti-social act in any university. Unfortunately, many professors are the slaves of an old-fashioned mode of understanding the education in engineering. It is not a good practice to solve a problem in any way; we must solve a problem with a good performance in terms of the limited physical and abstract resources of the world. An extrapolation of this idea can be done for computers where the physical resources and the abstract resource (as the processing time) are of the great importance for the engineers. We shall present some models and paradigms in parallel scientific computing starting from the real world models. The old Latin concept divide et impera is a good approach for the development of large engineering projects, for analysis and synthesis of the large-scale systems. The manager-workers paradigm is another paradigm for many parallel algorithms in engineering and business and the performance evaluation of the programs based on this paradigm is developed and presented. Engineering education from Romanian universities is analysed in context of the reconstruction process of the Romanian school. Some aspects of the politics in the area of human resources and infrastructure from universities are presented using target examples. The effects of the reform in engineering education are analysed in the context of the last decades and educational reform from Romania.

Abstract: Laboratory training as a means for comprehending taught in-class course material is faced with problems including large student numbers, excessive cost of experimental apparatus, and lack of multiple experimental setups, especially in cases where the use of instrumental prototypes providing realistic simulations are needed. Nowadays sensors, especially those operating in real-time, play an important role in edge-technology systems. Such systems collect information from the outside world, through multi-channel USB type data loggers. The outputs from these sensors are connected to the data logger channels for digitization, and entered for further processing to a computer system. The development of appropriate software is needed for data handling and display of results in a graphic oriented user friendly environment, so that all parameters and control signals are well comprehended. In this type of training we have to develope a prototype, aiming to simulate real incidents.

E-learning CAL software can be developed using Keithley's "Test Point" (versatile authoring tool) or other ways (i.e. visual basic) for training large audiences, simultaneously having visual contact of the real prototype. Students have the choice to collect experimental or software generated data for simulation.

Abstract: There is an increasing need for university graduates entering today’s job market to be skillful in adapting to novel work situations while sustaining a competitive advantage. To fulfill this requirement, students must adapt life long learning abilities in order to work successfully throughout their career development. In this paper I will argue that lifelong learning abilities can be enhanced by having curriculum activities structured in such a way as to allow students of varied expertise levels to participate in joint course projects. These courses ideally will all belong to the same prerequisite “ladder” allowing the students to be exposed to this unique teamwork experience throughout a student’s academic years/semesters.

Brief Biography of the Speaker: Dr. Nicholas Harkiolakis holds a Ph.D degree in Computer Science from the Agricultural University of Athens.

Plenary Lecture XXVIII

Modeling Muddy Flash Floods and Debris Flows

Professor Blaise Nsom

Université Européenne de Bretagne Université de Brest

LIME/LBMS/IUT de Brest. BP 93169. Rue de Kergoat. 29231. BREST CEDEX 3 France


Abstract: After long and intense rains in a mountainous region, large quantities of water flow in the torrents. For some reason, this flow can be obstructed by cross-linked branches and debris (natural dam). When the hydrostatic pressure exerted by the fluid exceeds a given yield value, the dam collapses and the fluid is released inside and outside the torrent bed, as well. Such scenario known as a dam-break flow can describe the initiation of certain geological flows, (debris flows, mudflows, etc.). As for any gravity current, the flow description depends on the time scale. Immediately after the dam collapse, the inertial forces are the dominant ones and this configuration can model a flah flood. Flash floods develop at time and space scales that conventional observation systems are not able to monitor, so reliable modelling remains a crucial step. At larger time scale, a viscous regime takes place where the viscous forces become the dominant ones and this configuration can model a classical debris flow. Debris floods develop in a long domain, i.e. a domain of space that is much longer than it is wide. They generally erode their bed and transport much energy and can move rocks and boulders upon very long distances. Both, the flash floods and the debris floods constitute dangerous phenomena for public safety and quality of life. The originality of the present approach is to consider these two flood waves as special cases of a single global model of a dam-break flow of a muddy fluid; depending on the time scale. The study was experimental, analytical and numerical, as well. The experimental study consisted in designing model fluids to be used in the laboratory experiments, characterizing these synthetic muds and monitoring the corresponding dam-break flows in the laboratory. While the theoretical study consisted in stating the equations of motion governing the different flows studied, and solving them in their non dimensional form, both analytically and numerically.

Plenary Lecture XXIX

The Use of Integral Transforms for Analytic Solution of Pre-stressed Thin Plate on Elastic Foundation under Axisymmetric Loading

Professor Dimitrios G. Pavlou

Technological Institute of Halkida (TEI-Halkida) Faculty of Mechanical Engineering

34 400 Psahna, Halkida, Evoia GREECE


Abstract: In the past, the model of a thin plate on an elastic foundation was mainly used in structural applications. Currently, thin plates or films of metal, ceramic or synthetic materials are bonded in the surface of machine structural parts or electronic devices to improve their mechanical, thermal, electronic or tribological properties. At these applications, the sub-grade of the thin plate can be simulated as a Winkler-type foundation, which reacts with pressure proportional to the deflection of the plate at each point. The plates in the above applications are loaded by vertical (distributed or concentrated) loads or bending moments, as well as by in-plane forces (compressed or stretched) due to e.g. temperature effects. A large number of analytical or numerical research works have been published to solve several boundary value problems of a classical thin plate or a thin plate on an elastic foundation. However, few research works have been published concerning the differential equation of a pre-stressed thin plate on an elastic foundation, due to its complexity. In the present work, an exact solution of the problem of an infinite circular thin plate on an elastic foundation under combined axisymmetric vertical and radial in-plane forces is attempted. For this purpose, the Hankel’s integral transforms and generalized functions properties are used. Numerical examples are included.

Plenary Lecture XXX

On the Eigenvalues Optimization of Beams with Damping Patches

Professor Veturia Chiroiu

Department of Deformable Media Institute of Solid Mechanics

Ctin Mille 15, P O Box 1-863, Bucharest 010141 ROMANIA

E-mail: [email protected] Web site: http://www.imsar.ro

Abstract: The paper discusses the behavior of beams with external nonlocal damping patches. Unlike ordinary local damping models, the nonlocal damping force is modeled as a weighted average of the velocity field over the spatial domain, determined by a kernel function based on distance measures. The performance with respect to eigenvalues is discussed in order to avoid resonance. The optimization is performed by determining the location of patches from maximizing eigenvalues or gap between them.

In Depth Analysis of the Analogies among Entropy, Information and Sensation. The Concept of Time in Thermodynamics

Professor Vassilis Gekas

Department of Environmental Engineering Technical University of Crete

GR 731 00 University Campus, Chania GREECE

E-mail: [email protected] Web site: http://www.enveng.tuc.gr/Labs/efmtfd_lab_en.htm

Abstract: In teaching Thermodynamics, to analyse the analogies of Entropy, Information, Sensation it might be proven very useful in helping the overall understanding of the students of those difficult concepts. Indeed all those three properties are expressed by similar equations, essentially the same one famous S=klnW equation , the only "epitymbion" equation (that is the equation which is engraved in the tomb of a Human, Ludwig Boltzmann). The teacher , to our opinion, should highlight and analyze the similarities and the differences of the various forms of this equation when applied to Entropy (Boltzmann) Information (Shannon) and Sensation (Heffner-Weber) respectively. The chemical and geometrical aspects of Sensation will be discussed, too. This lecture is based on the main idea that an additative accumulation in the W variable produces an increased Intensity of a feeling in the S variable which is logarithmically related to W. Beyond these three forms mentioned above an extension in to the concept of Time, a rather obscure and mysterious variable in the field of Thermodynamics, both the objective Time and the perceived Time (the "temps vaicu" in french, the Time as it is felt by Man.

Abstract: Since the advent of automobile, and design and construction of paved roads in the early 1900’s there has been a significant contribution made in highway related transportation research. While in the earlier decades bulk of highway transportation research revolved around planning, design and construction of roads, right-of-way acquisition, and highway financing issues, the focus has somewhat shifted in the last three decades. Recent research has revolved around issues related to traffic congestion and environmental impact. This presentation reviews the changing trend in highway transportation research over the last 100 years and presents some views for future research. Specifically, it emphasizes the need for a closer examination of the three-way interaction among vehicle, roadway, and driver for better planning, design, and traffic management. There is a considerable trade-off among these three entities when planning, designing, operating, and maintaining highways as well as highway traffic. The presentation concludes with some discussion on effects of globalization and sustainability in highway transportation research. Brief Biography of the Speaker: Dr. Manoj K.

Plenary Lecture XXXIV

The Role of Music Festivals in Creating Community

Professor Michelle Duffy The Australian Centre

School of Historical Studies University of Melbourne,

AUSTRALIA E-mail: [email protected]

Abstract: Held in parks, city centres, heritage sites, town halls, local pubs, or along main thoroughfares and streets closed specially for the occasion, festivals are a significant part of a community’s annual calendar. The social and cultural values of festivals are recognised by UNESCO, which has identified these expressions of as part of humanity’s intangible heritage. Maintaining such cultural practices is encouraged because it may help protect threatened cultural or ethnic groups, or be a means to give voice to those who have been in some ways muted or silenced. Although increasingly they have become a popular tool for initiating economic renewal—this is notable in cultural tourism literature and research, and are tactics readily taken up in local government policies and organisational strategies—these events are about adding value to our everyday lives. Festivals encourage community participation, enhance local creativity and foster community well being. One musician I interviewed in the course of my research pointed out that being part of a festival changes the nature of the place of our daily lives. This comment has always struck me, this connection between the festival and place, and in particular, the role of music in such a transformative relationship. Music elicits emotions. The emotions experienced through music are done so precisely because they cannot be expressed by any other medium, and this is one of music’s strengths. The music performances of festivals can draw us in and arouse emotions in us that encourage opening up to others. We clap, sway, perhaps sing along, smile, talk, and get caught up in the moment. Or we may even feel quite alienated, rejecting the sorts of performances we come across, grimacing, covering our ears and hurrying past. Drawing on festival case studies from Australia, this paper contributes to the literature on festivals and cultural tourism, through a focus on the possibilities offered by music as a medium for sociality, on music’s emotional effects as a means to explore how a community arises in the very acts of people engaging with the music of the festival. Brief Biography of the Speaker: Michelle Duffy was educated at Royal Melbourne Institute of Technology (BAppSci) and the University of Melbourne (PhD, BA Honours, BMus Honours). She is a cultural geographer, with specific research interests in the ways non-representational processes such as performance, music, dance and sound can be used to articulate and understand notions of place, identity, belonging, community cohesion, alienation and social well-being. These interests have led to research exploring public space, events, emotion and affect, and performative aspects of identity formation. Michelle is currently working on a number of funded projects that examine the role of the festival in urban, rural and remote communities. These projects seek to understand and define the processes of creating communal identity and social cohesion, with a particular focus on the ways music and sound are significant to the experience of the festival. Michelle teaches Australian Studies subjects and co-ordinates a number of international programs, which reflect her research interests in various aspects of Australian studies including Australian Indigenous cultures and people, Australian performance practices, cultural diversity in contemporary Australia, rural and public culture, as well as broader issues in cultural geography.
